From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

After rotation and climbing to approximately 50 AGL, with landing gear raised, pilot experienced a loss of power. While pilot was managing the engine controls, (mixture, prop, throttle, fuel pump), the aircraft lost altitude and crashed on the runway. A detailed inspection of the aircraft and powerplant was performed after it was moved to the privacy data omitted hangar. The following were checked: oil, fuel quantity and flow, cylinder compression, engine borescope, ignition plugs for spark after mag rotation. No obvious defects were found. The aircraft has both a mechanical and electric fuel pump. Pilot stated that the electric fuel pump was not on during flight and the circuit breaker was found tripped, although fuel flow was confirmed after applying electrical power. The failure could not be duplicated on the ground, therefore, a root cause could not established.

As the FAA filed it

AFTER ROTATION AND CLIMBING TO APPROXIMATELY 50 AGL, WITH LANDING GEAR RAISED, PILOT EXPERIENCED A LOSS OF POWER. WHILE PILOT WAS MANAGING THE ENGINE CONTROLS, (MIXTURE, PROP, THROTTLE, FUEL PUMP), THE AIRCRAFT LOST ALTITUDE AND CRASHED ON THE RUNWAY. A DETAILED INSPECTION OF THE AIRCRAFT AND POWERPLANT WAS PERFORMED AFTER IT WAS MOVED TO THE ^PRIVACY DATA OMITTED^ HANGAR. THE FOLLOWING WERE CHECKED: OIL, FUEL QUANTITY AND FLOW, CYLINDER COMPRESSION, ENGINE BORESCOPE, IGNITION PLUGS FOR SPARK AFTER MAG ROTATION. NO OBVIOUS DEFECTS WERE FOUND. THE AIRCRAFT HAS BOTH A MECHANICAL AND ELECTRIC FUEL PUMP. PILOT STATED THAT THE ELECTRIC FUEL PUMP WAS NOT ON DURING FLIGHT AND THE CIRCUIT BREAKER WAS FOUND TRIPPED, ALTHOUGH FUEL FLOW WAS CONFIRMED AFTER APPLYING ELECTRICAL POWER. THE FAILURE COULD NOT BE DUPLICATED ON THE GROUND, THEREFORE, A ROOT CAUSE COULD NOT ESTABLISHED.
